Show Us your Weathering, Detailing and Scratch building!

[ednadolski]

my surname is derived from sour cherries. I'm a fruit! 

According to online sources, my name has something to do with dwelling in a valley or lowland (or caves!)

But "Edmund" translates to "defender of the wealth"....  So Ed K., perhaps you had an ancestor who was a weathy cabbage farmer?

A little something I've been scratchbuilding for a while.



I haven't had time to write it up in any intelligent way, but it's the I83 bridge over Windsor St Yard.

Hey cabbage boy, I'm still not seein' this in Chrome or Safari, and I get an error 403 if I try to follow the URL directly.

Ed Cabbage-in-ski.
My last name is Surkosky. When I have to spell it over the phone, people often hear it as "k-i" instead of "k-y."
I usually tell them "K-y, like the jelly." They never forget after that.

Beautiful photo coos.  I agree that the weathering in the Difco cars really adds a lot.  Care to share your technique?  Also, what did you mean about cutting them down?  Ride height or side height?

Apparently you just don't have the right clearance... damn.

I blame Dropbox. I'll use my blog instead.

I cut down the length of the cars, I removed about an inch(not scale).Mec's cars were shorter than the stock Walthers cars I used. These are not 100% accurate, the sides were different, but I thought it was a reasonable compromise .Here's a proto pic:

I also made my own stone loads like in the link, rocks glued to a styrene base, so they're removable:



I weathered them by "splatter painting" them with with camo brown, red primer, and a dark wine red color. None of these colors covered completely, giving a random-ish rust. I then used the salt technique to cover this rust inside the car, and then shot black over the car, covering most, but not all, of the rust, wash off the salt and presto!....Here is another car I did the same way, but without the salt step...A little black chalk was added after the pics were shot, blending it even better and toning down the lettering..

@Ed Kapuscinski that looks pretty nice.

@Ed Kapuscinski that looks pretty nice.

Thanks! I've been working on it for a while, and since it's so prominent of a feature, I really wanted to get it right.

I based it on the bridge here. https://goo.gl/maps/lTvJ0

Even thought the actual one across the tracks is slightly different, I could easily get a photo of this one, so I went with it.

Needs plinths  .  My unschooled, engineering-by-eyeball says those columns look pretty dainty for the bridge's height and for all that road surface they're carrying way up at that hight.  And the fact that there are so many at each junction kinda reinforces that notion, so it would seem weight distribution would be required at the base.

[Ed Kapuscinski]

That's a good point.

I have run the thing by two civil engineers, and they haven't told me it's too wrong to go with, but I'll try and get one final sign off on that issue.

[sirenwerks]

I could be very wrong.  I'm just going by obesrvation.  But even the bridge visible from the Odenton MARC station, which has less road on top of it and is lower, has plinths.  I double checked my theory by looking at similar bridges to your model online and they either have plinths or, when no plinths exist, the columns are significantly beefier and there are less of them.  The latter is harder for you to do considering the clearance you have between tracks.  Of course, you also have to figure in your era, as this would be a relatively brand spanking new bridge, and not subject to today's infrastructure panic and rebuilding.

Sorry Ed, didn't mean to open a can of worms.

For a more detailed can of worms...

The BNSF and UP design standards state that a crash wall, or stronger column, need to be included in substructure units that are within 25-ft of the centerline of tracks.  This is to resist any collision force from errant rolling stock or locomotives.  The crash walls are typically constructed from below grade up to 6-ft exposed, they do not need to be the same depth as the columns.  Trying to judge the scale of the columns from the picture, it looks like there are 4 columns roughly 3 to 4 feet square supporting a superstructure 60 to 70 feet wide, this is reasonable.  I would suggest that the pier caps (the beam across the top of columns) be slightly larger to support those deep girders, in the range of 5 to 6 feet square.

On the superstructure, you should provide an overhang of the deck from the exterior girders, probably no more than 4 feet.  The bridge in the Google link is supported by what appear to be concrete AASHTO I Beams, where as the model is using concrete bulb tee beams.  A bulb tee has a much wider top flange than the AASHTO beams, so it does not need to be placed so near the edge of deck.  The girder lines also look to be spaced too far apart, somewhere in the 7 to 9 feet on center range would be more realistic.

Hope it helps!

Paper Mill rotary kilns getting closer to done.

[ Guests cannot view attachments ]

Still need to finish painting and weathering, especially the concrete portions. GMM handrails and walkways will complete things.

Kilns are spraybombed with two shades of primer, plus some gray and blindfold. I think the airbrush will be needed to get the vertical streak patterns I see on the real things.

That's some serious p0rn right there. That scene is amazing!
